SEAL LOCK.

Application filed May l16, 1927. Serial No. 191,573.

geous in that it indicates whether or not the satchel or other container has been `opened by an unauthorized person. Moreover the card, carrying the owners name, furnishes a readily visible means of identification, very useful when the satchel is carried by a porter or whenever it is left in a` public place, suchas a check room.

An object of the presentinvention is to make a lock of this character which is simple in construction and which may be readily designed for easy attachment to portable traveling bags. The lock made in .accordance with my invention is so designed that theiowners card may constitute the sealing member and thereby serve also as a means of identification.

One form of mechanism for carrying out my invention is illustrated in thedrawings wherein Fig. 1 is a view of one form of the lock closed; Fig. 2 is a similar viewshowing the cover in partly openV position (as indicated in broken lines in Fig. 4) and with the seal mutilated; Fig. 3 is a view showing the interior lock mechanism; Fig. 4 is a section taken through the lock on a plane indicated by the line 4-4 in'Fig. 2; Fig. 5 is an elevation of a safety deposit box equipped with a sealed lock made in accordance with my invention; Fig. 6 is a side elevation of a satchfel emb-raced by a chain carrying my seal lock.

The form of seal lock which l have shown in Figs. 1 to 6 inclusive comprises a hollow casing 10 which has an opening 11 along one side and an opening 12 adjacent one end thereof. A bolt 13 is slidably mounted within the casing and has keeper portions 14 and 15 associated therewith. Any suitable form of mechanism may be utilized for locking the bolt iu. closed position when it is snapped shut, but that illustrated comprises a spring` 16, one end of which is attached to the casing, and the other endy of which, is adapted to engage a notch 17 in the bolt and to hold the belt in locked position. The spring may be moved out ot engagement with the bolt and the bolt may then be moved to open position upon the turning of a key 18 which inserted thro# jab the ke/"hcle190 A cover 20 is illustrated as being hinged at 21 to one end ot' the casing and as havin# downturned flanges on three sides thereoi which entend over the edge of.' the casing when the cover is closed. rlhe cover also has a sight opening 22 behind which a card 23 may7 be placed before the cover is closed. This card normally covers the keyhole and thereby prevents access to the opening, unless the card is mutilated, so long as the cover is locked.

To lock the cover to the casing, l have shown the cover ashaving an opening` 25 in the fiange portion 26. "JV hen the cover is closed, the keeper 15 entends through this opening and also through an opening in the casing in registration with the opening 25. The locked position ot the bolt is shown in Fig. 4.

To lock the device described to a container such as a hand l have shown an opening 7 extending along one side of the casing and l have illustrated the keeper 14 as being arranged to project across the opening and to enter the passageway 31 in a flange 32. The container to be locked may have a staple or similar fastener which enters the opening' 80 and i s locked when the keeper 14 is moved to the locked position. Or, as in the case of the satchel S in Fig. 6, the bolt 14 may pass through the end link of a chain C anchored to the lock and surrounding the container. Thus, thefcontain'er as well'as the seal is locked by a single movement of the bolt.

In Fig. 5,1 have shown my invention as applied to a safety deposit box 35. Inthis arrangement the casing is attached to the front wall of the box in such manner that the side having the opening 30 is adjacent the upper edge ot the front wall 36. The keeper 14a when in locked position will then pass through the staple 37 which is fastened to the casing and through another staple 38 which is tasten'ed to the box lid 39. The sealed cover 20a is locked simultaneously with the locking of the boX in the same manner as that heretofore described.

The box lid may have a flange 40 which eX- tends downwardly over the lid 2OaN and func-- tions to prevent removal ot the lock as a unit from the wall of the box so long as the box is locked.

A device made in accordance with my invention is advantageous in that it provides a simple and effective means for locking a portable container, and at the same time insures protection against surreptitious opening ci the container. The card which chases the keyhole 'functions then, not oniy to appraise theI owner oi the condition oi' the container but` also serves as a ready means oi identiiication. As applied to safety deposit boxes my vinvention makes a simple form of lock Which 0bviates the necessity for an eXtra key inr'the hands of the custodian, since the owner may make any indicia of his own design-on the hiddeii suriace oi the card.

I claim 1. In a device oi the character described, the combination et a casing, ay hinged cover therefor having a sight opening, said cover being adapted to hold a card between .it and y the casing,a iockiiig bolt niovably mounted in the casiirig` iindserviiig the double purpose of locking a suitable container and simule taneously locking 1the cover to the casing, said locking bolt being controlled by the' keyv in a region shielded by the card.

,2Q In a device of the character' described, the combination of a casing, a hinged cover therefor, having a sight opening, said cover being adapted to hold a card between it and the casing,I alocking bolt movably mounted in the casing andserving the double purpose of locking a suitable container and .sii'niiltane- :ously-locking the cover to ,the casing, and
